Here's a lovely #blueprint on a new study from our lab led by @royeyono.bsky.social.
tl;dr: it implies that there may be interneurons whose role is to normalize credit assignment signals during learning.

This is an important one. That soma-targeting interneurons can do background subtraction and gain modulation is well understood. But the roles of dendrite-targeting interneurons in normalizing top-down learning signals have not been studied in detail.

How do neural circuits in the brain implement normalization? 🧠
In our new paper, we show that just normalizing sensory input isn't enough. Crucially, we must also normalize the error signals! 🧵👇

Normalization is a critical operation in neural circuits. In the brain, there is evidence that normalization is implemented via inhibitory interneurons and allows neural populations to adjust to chang...
Really stoked to see this project in (pre)print. On how to implement normalization-via-inhibition in ANNs, and what it might mean for inhibition in the brain. ⚖️
Great job @royeyono.bsky.social and the team 👏👏👏
